FOR IPNEUMATIC SOLID TIRES.

Application filed. December 5, 1921. Serial No. 520,096.

fragmentary portion of my improved rim mounted upon an automobile wheel. employing a demountable rim. 2 is a sectional view of Fig. 1. Fig. 3 is a side view of my rim seen in Fig. 1 with a part in section to disclose constructional features of the device. Similar numerals of reference indicate corresponding parts throughout all the figures ot the drawings.

In mounting a tire casingin a demountable rim. it has previously been necessary to decrease its diameter suiliciently to allow the casing to slip over the flange thereof. Most demountable rims are of a single piece of sheet metal rolled ring-like with the ends brought to a membering relationship. This permits oi. a reduction in diameter for mounting the casing as is well understood in the art. When the casing was in posit-ion. the rim was then expanded to its normal. size. It frequently happened that this was diliicult to accomplish, especially when the mechanic was not suppliedwith the necessary tools and accordingly, the rim was beaten with a hammer and pried. forced or twisted until eventually it became misshapenand worthless. By means of my invention, this trouble entirely obviated and a. rim is provided that is very substantial and one upon which a casing can be readily mounted. In my invention, as will be later disclosed, two ring-like elements, each haw ing a flange along its outered 'e portion also have band-like elements, each integral with its flange element on its own section; one band element of one section extends towards and in the combination entirely supports the band element of the other ring element. since the band element of? the first section is of the full Width necessary to reach quite across the telly band on the Wheel itself; and this first section also carries on its inner face, at spaced intervals, enlarged threaded portions be later shown. rep stor with Ulltfilflilffi rip-- posi'tely positioned in the flange oi the other section and accommodate securing bolt ole ments and whereby the combination is el tented.

Referring to the drawing my improved rim coniprises two ring-line members 10 and 11 which shown in Fi l and 2 are in combination upon obile wheel it? arranged for a demountable 1111]. being pro vided with. the tapering; steel flanged telly band -3 disclosed. The member 10 preferably fabricated as a hoop or band whose inner diameter is of a size "to pass the tapering telly band 13 to a contact with the flange 14 thereof. The member 10 is provided with a laterally and outwardly extending flange member 15 along one edge thereof and of proper size and shape to accommodate either a. sh: side or clincher tire casing: the opposite side 1.6 of the member 10 constitutes a band portion and tapers outwardly as 1lisclose1l in Fig. 2. 7

The member 11 is provided with a flange '7 similar to the flange l5 and this in the assembly bears against the opposite head of the tire casing as disclosed. while the opposite side 18 of the member 11. larger in diameter than the corresponding portion 16 of the member 10 is likewise outwardly tapered.

it will be noted thutu l'lauiic l7 is iuwardly arranged "from the member l3 and on the side opposite the flange l7 and at spaced distances, holes are provided through wiich bolts 19 are passed which pass also through holes such as 20. transversely ar ranged through enlarged portions oi the member 10 and into which the screw.

To mount tire casing; 22 upon .is wheel 12, Figs. 1 and 5 the member "10 brou. into position from one site with its i contacting the head of the c member 11 is brought into position from the opposite side oi the casing with its tapering; section arranged intermediate the cool and the tapering section of the member jlfif The several bolts l9 are then inserted through the registering holes 20 and screwed up, thereby r 'idly clamping the members ill and 11 together in. which position they sup port the tire casing. The assemblage is then slipped over the tapering telly band 13 and the customary rim retaining lugs 23 when Set by the bolts 2% maintain. the assemblage upon the wheel 12.

To remove the casing, it is merely neeessary to remove the lugs 23 and the bolts 19, then the member 11 is witluh'an'n. Sometimes the casing will remain on the member 11 and. sometimes on the member 10, whichever is the case, the casing is then lifted from the retained ring member.

The tapering or angular formation of the parts 16 and 18 enables the clamping bolts 19 to draw the par-ts to a close and tight fit, whence they act as a unit.

Finch modifications may be employed as lie within the scope of the appended claim.

Having fully described my invention what I new claim as new and desire to secure by Letters Patent is In a rim oi the class described; two ringlikeeleinents, the first element having aflange as an outer edge portion and a bandlike tapering section integral therewith; the second element likewise having a flange as an outer edge portion and a band-like tapering; section integral therewith and of larger diameter than the first mentioned band-like sect-ion. and upon which it is arrangeable in combination; the first element having a plurality of enlarged portions, integral there with, arranged. transversely thereto at spaced distances apart on the inner side of its hand section, each enlarged portion having a bolt receiving hole axially aligned therein and threaded at its inner portion; the flange of the second element extending troniboth sides of its band section and bolt receiving; holes therein and bolts one for each bolt receiving hole registering with the bolt receiving holes of the enlarged trans verse portions of the first element for the purposes substantially as specified.
